Hi, I was checking out my scan history in avast, oddly the scans which found no malware has a red exclamation mark on its left and the scans which actually had found malware has green tick on its left. I think the icons are swapped for the results.
Same issue is also their in AVG Free running in another machine. My machine is running avast! premium security running 21.4 update. Refer attached screenshot (taken when running free version, same happens with premium security too).
